Results of surgical treatment for displaced acetabular fractures

Abstract text (incl. references and figure legends)

INTRODUCTION: Acetabular fractures are often associated with politrauma and the treatment of these fractures remains a challange. The aim of this study is to perform a retrospective analysis of complications following the surgical treatment of displaced acetabular fractures.

MATERIALS & METHODS: Between January 2011 and October 2020 a number of 147 patient with displaced acetabular fractures were treated surgically. According to the Letournel classification (1), the most common fractures types were: posterior wall fractures (28.7%), transverse fractures (21%) and transverse and posterior wall fractures (20.3%). Clinical outcome was evaluated using Merle d"Aubigne score modified by Matta (2).

RESULTS: Intraoperative complicatons were vascular injuries (8 cases) and damage to the static nerve (4 cases). Quality of reduction based on Matta's criteria showed anatomical reduction in 94 cases (63.9%), imperfect reduction in 34 cases (23.1%) and poor reduction in 19 cases (12.9%). Two-year follow-up results (available for 106 patients) were excellent in 46 cases (43.3%), good in 38 cases (35.8%), fair in 12 cases (11.3%) and poor in 10 cases (9.4%). There was a statistically significant correlation between quality of reduction and clinical results. Other complications were heterotopic ossifications. osteonecrosis of the femoral head and arthrosis. Hip arthroplasty was the final solution for 16 patients (15%).

CONCLUSIONS: Despite the relatively large number of complications, surgical treatment for displaced acetabular fractures is the optimal choice.
